Summary
Smartphone use duration inversely correlates with hypertension risk in adults over 50. Longer smartphone use was linked to lower hypertension risk, suggesting it
Area of Science:
- Gerontology
- Public Health
- Epidemiology
Background:
- Smartphone use significantly impacts human health.
- The relationship between smartphone use and hypertension risk in older adults (≥50 years) is not well understood.
- This study investigates this association in a Chinese population.
Purpose of the Study:
- To explore the association between smartphone use duration and hypertension risk.
- To identify smartphone use as a potential indicator for hypertension risk assessment in older adults.
Main Methods:
- A population-based cross-sectional survey (Fujian Provincial Eye Study) conducted from 2018-2019.
- Included 8,211 participants aged ≥50 years.
- Analyzed smartphone use data and blood pressure measurements using univariate and multivariable logistic regression.
Main Results:
- Hypertension risk significantly decreased with increased smartphone use time.
- Higher smartphone use time was associated with elevated systolic blood pressure (SBP) but not diastolic blood pressure (DBP).
- Smartphone use duration, age, BMI, diabetes, and education level were independent predictors of hypertension risk.
Conclusions:
- Smartphone use duration shows a significant inverse association with hypertension risk in adults aged 50 and older.
- Smartphone usage duration is a potential indicator for assessing hypertension risk in this demographic.
- Further research may elucidate the mechanisms behind this association.

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

3.7K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

787
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...
